BP93420D-II Differential Pressure Transmitter With DIN For Liquid
Test Differential Level Sensor
BP93420DII Differential Pressure Transmitter
Introduction of differential pressure transmitter sensor:
The BP93420DII is a differential pressure transmitter equipped with
a diffusion silicon piezoresistive sensor, featuring dual pressure
ports for connection to pipelines or impulse lines. This device is
designed for measuring pressure differentials in both gaseous and
liquid media, capable of handling overpressure, vacuum, and
near-static conditions.
The sensor utilizes a solid-state ceramic diaphragm that deforms
under applied pressure, with the resulting strain producing a
proportional change in resistance. This signal is processed by an
integrated electronic converter within the housing, which outputs a
standardized 0–10 V or 4–20 mA signal.
Installation is facilitated by threaded connections, making the
transmitter suitable for diverse industrial and sanitary
applications. Typical use cases include monitoring pressure
differentials in heating systems (between supply and return lines),
as well as controlling filters, fans, and compressors.
Product Featuresof differential pressure transmitter sensor:
- The transmitter features a stainless steel structural design,
making it compact and easy to install
- It undergoes strict temperature compensation and aging screening,
ensuring stable and reliable performances
- The electrical interface can be selected as a plug-in or direct
wiring option.
Applications of differential pressure transmitter sensor::
- Suitable for measuring differential pressure of various gases or
liquids in pipelines of industries such as petroleum, chemical,
power, and hydrology.
- Applied in industrial on-site processes such as petroleum,
chemical, metallurgy, power generation, and hydrology
- Pressure measurement for pipelines and furnace chambers

1. When selecting the product, please ensure that the measured
medium is compatible with the product's contacting parts.
2. To ensure reliable operation, it is recommended to install a
three-valve manifold between the measurement point and the
transmitter, ensuring a slow and uniform pressure application to
the positive and negative pressure chambers of the transmitter.
3. During installation, it is advisable to position the pressure
interfaces at both ends horizontally to minimize the impact of the
installation location on the product.
4. For special requirements such as strong vibration, instant
impact force, strong electromagnetic interference, or radio
frequency interference, please inform our company and specify these
requirements in the order
